Bahut FEARS lag rha hai T_T

My syllabus was completed before the exams started and I have also practiced plenty throughout the year. Did pyqs during both pre boards. Solved 6-7 past papers. I have been attending Ritik sir's marathon for question practice, which will be completed by tomorrow.
What should I do from tomorrow ?? practice more questions ? or do past papers but they are kinda time consuming ? practice harder questions from somewhere ? anything else ????

I am scared af because I am pretty average in math and scored 65 in 1st PB and then 73 in 2nd PB. Also, my speed is kinda slow when it comes to math so any advice on that is also appreciated. I haven't done RD or RS, but I have practiced from U-Like (not complete)

PLEASE HELP !
